My lg mod# 42LV4400-UA tv will not turn on


LG had a serious quality problem with the main board and there is a bad solder joint on all original 42lv4400 and 47lv4400 units.It will manifest the problem either went it gets warmed up and then power down itself or never power up. The red light stays on and the TV does not respond to manual or Remote input.
A factory reset will not fix this problem. It takes a "NEW" main board. The big white label on the back panel has the original manufacture date and LG will send out a factory authorized technician to repair the unit within the first year after that manufacture date.call 800 243 0000 to schedule a home visit to get the repair done.
By the Way, a 42lv4400 main board will not work in a 47lv440 even though they look identical. The reverse is also true.

Consider having a shop look at it--one who does authorized warranty work.

You might also call LG to see what if any known issues for this model are.

CAN'T FIND MANUAL TO DOWNLOAD


You can download the manual here: LG Manual.
It's a .pdf file so you will need Adobe's Acrobat Reader if you don't already have it.

I have a lg DVD-RAM Model no GH22NP20 its not run data cds & DVD-RAM.


need to check firmware version then update it

Here's how to get LG's Auto Firmware Updater
Go here :
http://www.lge.com/support/software.jsp
Select
> Location = North America > USA/ Canada
Then
> Product = DVD-ROM (writer)
> Operating System = Vista
> Subject = LG Auto Firmware Download


Download the .zip file to your Desktop
You'll need to "Extract All" from the .zip
and then run the setup file
You'll need to allow Internet Access ( AV/IS )
The Updater will probably need to Update itself - before being active


To Manually Search For Firmware Updates
> Product = DVD-ROM (writer)
> Operating System = Vista
> Subject = Firmware

Look through the Listings for your Specific Drive
I would recommend Disabling the LG Auto Firmware Updater
- from Windows Start-up
You can open the Updater at any time - from All Programs
